A method may include receiving, via a processor, a frame of image data, such that the frame of image data may include an active portion and an idle portion. The active portion may include data for presenting one or more images via a first display of a first electronic device. The method may also include receiving a signal from a second electronic device during the idle portion of the frame of image data, such that the second electronic device is separate from the first display. The method may then involve initiating processing of the frame of image data in response to the signal being received from the second electronic device.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, comprising logging, via the processor, a line number of the plurality of lines in a memory in response to the amount of time that corresponds to the idle portion expiring and the signal not being received from the second electronic device during the amount of time.
4. The method of claim 3, comprising generating an interrupt in response to receiving the signal.
5. The method of claim 3, adjusting the amount of time based on the line number.
6. The method of claim 1, comprising toggling a line number of the plurality of lines after an additional amount of time associated with the active portion expires.
7. The method of claim 1, wherein the signal comprises a pulse.
8. The method of claim 1, wherein the idle portion of the first frame of image data immediately precedes a vertical front porch (VFP) portion of the second frame of the image data.
9. The method of claim 1, wherein the signal comprises a toggle.
11. The electronic device of claim 10, wherein the signal is configured to cause the image processing circuitry to cause the display and the additional display to synchronously present one or more additional images of the additional frame of image data.
12. The electronic device of claim 10, wherein the image processing circuitry is configured to log a line number of the plurality of lines in a memory in response to the amount of time that corresponds to the idle portion expiring and the signal not being received from the second electronic device during the amount of time.
13. The electronic device of claim 12, wherein the image processing circuitry is configured to adjust the amount of time based on the line number.
14. The electronic device of claim 10, wherein the image processing circuitry is configured to adjust the amount of time based on the signal being received during the active portion.
17. The image processing circuitry of claim 15, wherein the one or more operations comprise tracking a beginning of each line of the plurality of lines.
18. The image processing circuitry of claim 15, wherein the one or more operations comprise logging a line number in a memory in response to the signal not being received from the second electronic device, wherein the line number corresponds to a line of the frame of image data.
20. The image processing circuitry of claim 19, wherein the one or more operations comprise adjusting the duration of the period of time based on the line number.
